Summary:
Similarly, the HasMips64 on the 64-bit move InstAlias is a test for 64-bit
GPR's.

This commit reapplies 205018. After 205855 we should correctly vectorize
intrinsics.

llvm-svn: 205965

Summary:
It is now the smallest superset for these ISA's.

FeatureMips4 now contains FeatureFPIdx since [ls][dw]xc1 were added in MIPS-IV.
Made the FPIdx feature bit lowercase so that it can be used in the -mattr option.

Depends on D3274

-> 15       a = 4;

FIXME: Could we use SmallString here?

GCC 4.8 complains with:
  warning: enumeral and non-enumeral type in conditional expression

Although this is silly and harmless in this case, add an explicit cast to
silence the warning.

If we crash, we raise a crash handler dialog, and that's really
annoying.  Even though we can't emit correct IR until we have musttail,
don't crash.

The immediate cost calculation code was hitting an assertion in the included
test case, because APInt was still internally 128-bits. Truncating it to 64-bits
fixed the issue.

Revert "For the ARM integrated assembler add checking of the alignments on vld/vst instructions.  And report errors for alignments that are not supported."

It doesn't build with MSVC 2012, because MSVC doesn't allow union
members that have non-trivial default constructors.  This change added
'SMLoc AlignmentLoc' to MemoryOp, which made MemoryOp's default ctor
non-trivial.

This reverts commit r205930.

As it turns out the source of the sunkaddr can be a constant, in which case
there is not an instruction to delete, causing the cleanup code introduced in
r204833 to crash. This patch adds a dynamic check to ensure the deleted value is
in fact an instruction and not a constant.

Enable data formatters to see-through pointers/references to typedefs

For instance, if Foo is a typedef to Bar, and there is a formatter for any/all of Bar*, Bar&, Bar&&, then Foo*, Foo&, and Foo&& should pick these up if Foo-specific formatters don't exist

AVX supports logical operations using an operand from memory. Unfortunately
because integer operations were not added until AVX2 the AVX1 logical
operation's types were preventing the isel from folding the loads. In a limited
number of cases the peephole optimizer would fold the loads, but most were
missed. This patch adds explicit patterns with appropriate casts in order for
these loads to be folded.

The included test cases run on reduced examples and disable the peephole
optimizer to ensure the folds are being pattern matched.

FoldConstantArithmetic() only knows how to deal with a few target independent
ISD opcodes. Bail early if it sees a target-specific ISD node. These node do
funny things with operand types which may break the assumptions of the code
that follows, and there's no actual folding that can be done anyway. For example,
non-constant 256 bit vector shifts on X86 have a shift-amount operand that's a
128-bit v4i32 vector regardless of what the first operand type is and that breaks
the assumption that the operand types must match.

Moving it into a struct makes things work because it implicitly marks
the function as inline.  The struct is unnecessary if you explicitly
mark the function inline.

This patch changes how we determine if padding is needed between two 
bases in msvc compatibility mode.  Test cases included.

In addition, a very minor change to the printing of structures to ease
